I've made wooden fences based on idea I’ve found in Dreispitz blog. I designed my own “fence machine” using only plasticard. In 2-3 evenings I managed to build 48 pieces and year later I’ve painted all of them using airbrush for the first time.
I’ve made modular muddy roads for my Bolt Action 1939 project. The biggest problem I had was matching my electrostatic grass mat with electrostatic grass made by the same producer. I didn’t check it before so after applying grass, I’ve found grass colours were totally different. I’ve spend few hours watering grass (glued with PVA glue) and then removing it with my thumb. I’ve made my own mix of Noch grass (50/50) and it works almost perfect.
